When the venerable theater opened in 1932, vaudeville producer Samuel Lionel "Roxy" Rothafel—who dreamed up the grand venue—wanted his own equally posh digs within the building. To wit: Rothafel had an exclusive suite constructed on the fifth floor. Although the theatrical impresario never actually moved in, the space was kitted out with extravagant details. Interior designer Donald Deskey added Art Deco elements, including 20-foot-high domed ceilings, cherrywood walls and an intimate dining area. Today the area is called Roxy's Suite, and is reserved for Radio City performers and VIP attendees. (Elton John, Dave Matthews and Paul McCartney have all hung out there.) You can get a peek at the apartment during the venue's regular Stage Door Tour. 1260 Sixth Ave at 50th St (212-247-4777, radiocity.com)
